AI 中文摘要
我们研究了两个与热浴耦合的铁磁一维伊辛链系统，它们以恒定速度相互移动从而偏离平衡态。我们表明，即使在适度速度下，两条链之间的磁摩擦也会显著增强系统的有序能力。特别是，在逆温度β、伊辛耦合J和滑动速度v下，动力学对其初始磁化强度的记忆时间从v = 0时呈指数增长（\(\exp(O(\beta J))\)），到v > \(v_c\)（\(v_c\)为小常数）时增长为\(\exp(O((\beta J)^2v\ln v))\)。磁摩擦因此为一维磁体中参数化减缓热化提供了一种简单机制。
英文摘要
We study a system of two ferromagnetic one-dimensional Ising chains coupled to a thermal bath, which are driven out of equilibrium by being moved past one another at a constant speed. We show that even at modest speeds, magnetic friction between the two chains significantly increases the ability of the system to order. In particular, at inverse temperature $β$, Ising coupling $J$, and sliding speed $v$, the dynamics retains memory of its initial magnetization for a time that increases from $\exp(O(βJ))$ at $v = 0$ to $\exp(O((\b J)^2v))$ when $v>v_c$, where $v_c$ is a small constant. Magnetic friction thus provides a simple mechanism for parametrically slowing down thermalization in a one-dimensional magnet.
